Characterization of cis-polyisoprene produced in Periploca sepium, a novel promising alternative source of natural rubber.

ABSTRACT: Natural rubber is an important industrial raw material and is almost exclusively produced from Hevea brasiliensis latex. Because H. brasiliensis is limited its cultivation to specific tropical regions, the insufficient capacity of natural rubber has become increasingly urgent. To develop a novel alternative plant for natural rubber production, we selected a perennial shrub Periploca sepium, which is widely distributed from tropical to temperate regions. P. sepium can produce latex and contains the rubber component polyisoprene with a high-molecular-weight distribution ranging from 10⁴-10⁶. Its main chain structure was identified as cis-1,4-polyisoprene, similar to that of H. brasiliensis. The polyisoprenes were observed to be present mainly in the secondary phloem adj
